SPRAY GUN.
Application led May 10, 1921, Serial No. 468,313. Renewed October 6, 1924.
. 8 This invention relates to .a new and useful 1mprovement 1n extension spray guns for spraying paints, varnish and the like, the obnection with the adjacent rubber hose section whereby air Amay be supplied to the spraying head. Sections'may be added or removed for the purpose of lengthening or shortening the handle. 'Each 'rubber hose section is held to its companion metal pipe section by means of sliding clips which may be adjusted along the metal pipe sections for the purpose of releasing the rubber hose section to permit manipulation thereof in making connections between'the rubber hose secf tions, after which the clip, or clips, are slid towards the coupling to hold the end of the rubber hose sections in position on the metal pipe sections,
The spray'head is vertieallyadjustable on the upper end of the extensible handle and the lower end o f the handle is preferably formed of a casting forming a hand-grasp beneath which are cocks for controlling the flow of paint and flow of air to the spray head. The paint cock is preferably a twoway cock, while the air. cock is a three-way cook, which, when the supply of air is cut ofi from the spray head, will open the air in the Sectional rubber hose to atmosphere thus releasing the spray head from pressure.

On the drawings, 1 indicates a casting preferably made of aluminum and having an air conduit or passage 2'formed therein which opens through the end of the barrel into a Vchamber formed by an adjustable nozzle'3. The construction of this nozzle forms no part of my present invention, it being the subject matter of a companion application filed by me on the tenth day of May, 1921, Serial No.` 468,314.' However, I am'not "confined to the particular nozzle shown, as the nozzle sh-Own 'in my Patent No. 1,382,641, granted June 28,
1921, could be used. Y
4 is a nipple screwed into the end of the barreland which supplies the paint at or 'near the central opening in the nozzle from a 75 passage or conduit 5. 6 indicates a valve for closing communication between conduit 5 and a paint chamber 7. This valve 6 is nor- .mally held in a closed position by means of .ya spring 8 bearing thereagainst and seated in 80 'a removable capor plug 9,. The stem 10 O f the valve passes through a packing gland 11 .and has its lower'vend-threaded to receive a. .nut 12 constituting the limit or stop for arresting the upward movement of valve 6.
13 indicates a piston mounted in a chamber 14 and under which leads a port 15 from the air conduit 2. Thus, when compressed air is admitted to the nozzle-chamber, it will also be admitted to the underside of piston 13 and raise said piston so that valve 6 vis unseated and paint from chamber 7 will pass into conduit 5 andv thence through nipple 4. The spray head casting- 1 is provided with a threaded boss 1a by'whieh a flexible air 95 hose, preferably of rubber, may be attached for the purpose of supplying compressed air to the conduit 2.
16 indicates a flexible hose which is slipped over a tapering nipple 17a having a hexago- -nal head-17 by which the same may be held .Y rule fits into the beveled seat in the boss 1a,
and a detachable air-conduit coupling is thus provided.
21 indica-tes an angle coupling by which the spray head is secured to -the upper end of a hollow casting 22. This hollow casting has a stepped concentric bearing 23 on a hollow casting 24. A butterfly nut 25 co-operates with a centrally arranged pivot bolt for the purpose of holding the castings 22 and 24 in close contact. llVhen said butterfly nut 25 is loosened, casting 22 may be rotated about the pivot bolt 26 as an axis, after which the butterfly nut 25 may be tightened for holding casting 22 and its carried spray head in adjusted position. The head of the pivot bolt 26 andthe inner end of the butterfly nut 25 are preferably beveled so as to make .a tight joint.
27 indicates the 'upper section of a metalV ipe having threaded engagement with the ower end of casting 24. 28 indicates a clip, see Figure 9, slidingly mounted on the metal pipe section 27 and the flexible tube sect-ion 16. The purpose of slidingly mounting this clip 28 is to provide for a relatively long free end of rubber tubing. In practice, the metal pipe sections are first secured together. These sections are about three feet long and as many are used as desired, depending upon as shownin Figure 1.
The coupling between the flexible pipe sections is best seen in Figure 6, and preferably consists of a sleeve 29 arranged on one of the pipe sections to provide an abutment for a universal coupling sleeve 30 which has.'
threaded engagement with a hexagonal headed sleeve section 31 arranged on the other pipe section. The end of the pipe upon which the threaded sleeve 31 is screwed is preferably beveled (as at 31) so as to en- 'ing 42a to atmosphere.
gage a beveled seat in the sleeve 31, and the outer end of the sleeve 31 is preferably beveled, (as at 31") so as to engage `the seat in the end of the pipe 27a which carries the i universal coupling 30. The female flexible hose eoupling heretofore described may be used 1n connecting the intermediate sections of hose, the male member of which consi-sts of a hexagonal headed member 32 having threaded portions on each side of its head and a tapered tubular extension 32a over which flexible tube section 16a is arranged, there being a threaded sleeve 33 having an inwardly extending flange 33L for gripping and tightly securing the end of the 'flexible tube on the tapered tubular extension.
35 indicates a casting having an air conduit 36 and a paint conduit 37. This casting forms a hand-grasp into the upper end of which are secured the lower metal pipe section (for paint) and the lower flexible tube section (for air). 38 indicates a twoway cock having a suitable handle arranged in a valve casing 39 and preferably drawn to its seat by means of a spring 40. This cock is employed for the purpose of admitting paint to the casting 35 and metal pipe sections to the spray head. A flexible pipe 41 is coupled to the lower end of valve casing 39 and leads from a source of paint supply, such as a paint tank (not shown). The paint in this tank may be under a low air pressure sufficient to'force the same up to the spray head. ln practice, I have found that from five to ten pounds pressure on the paint in the tank will answer all practical purposes and that the compressed air supply to the spray head may range from fifty to one hundred pounds pressure in securing good results.'
42 indicates a valve casing having a threeway valve 43 arranged therein. This valve is preferably tapered likevalve 38 and may be provided at one end with a handle for manual operation and a spring on the opposite end for holding said valve to its seat, as described with relation to valve 38.
In operation, as many sections may be used in the extension handle as are needed, the spray head being located on the upper end of the top ysection and adjusted as required. The operator may grasp the casting 35 with one hand and by taking hold of one of the sections above the casting guide the V tween said neeaiee any time, the valve 38 is first closed and then the valve 43 operated tolshut ed the supply of compressed air to the spray head and peru.
mit a leakage of the compressed air from the spray head. To again start spraying operations, the 4air valve is preferably first opened, and then the paint valve manipu-I lated until the required amount of paint is supplied to thespray head.
